T 0 all who/m 'it may concern.'

Be it known that l, FREDERICK FARMER, a citizen of the United States, residing` at llriorcester, in the county of lillorcester and State of Massachusetts, have invented a new and usefu Wire-Bending Device, of which the following is a specification.

This invention relates to a wire bending device or machine, capable of forming a series of loops in a wire. While the invention is capable of general use, it is especially adapted for making jacquard needles and articles oi that kind in which a wire is provided with two or more loops, at least one of which is elongated in the direction of the wire, although it is to be understood that the invention is capable of use for the production of any other similar' article from wire or the like. lt will be d scribed f'ith particular reference to its use for the purpose of making suoli jacquard needles.

llilith this end in view the invention comprises in its complete form a series oi wire bending devices adjustable with respect to cach other, so that the distance between the bends may be regulated at will. rThe iirst of these devices is a means for forming a bend at the end of the wire, and comprises also a device for turning the wire about a center when its end is held in the position in which it is bent so that the body of the wire itself turns around 180 degrees in the niachine and comes naturally into contact with the second bending device so that it is accu rately located in position for the operation thereof. This second bending device coniprises a loop former which operates to turn the wire again around a pin and form a loop. ln its preferred form it operates to produce an elongated loop and bends it-about two pins instead ci one. This brings the end of the wire again into position at 1S() degrees from the original position of the wire in the first bending device and in contact with another loop ornier which forms another loop therein. lt will be understood, of course, that the relative locations and arrangements of these parts may be varied, and that the invention involves combinations of any two or more of them without the others, and that, of course, when it is not necessary to form all of these loops, one or more of the above mentioned devices may be removed from the machine or otherwise prevented from operating.

ln the form in which the machine is illustrated, the various parts are operated by hand, and this is a convenient and simple way ci instructing` and operating the machine, but of course, it is not necessaryT that the' parts should be operated by hand, as they might be connected up in any ordinary way for mechanical operation.

Reference is to be had to the accompanying drawings which show a preferred embodi ment ofthe invention, and in whicht Figure 1 is a plan thereof. Fig. 2 is an end elevation showing the supporting bar in section. Fig. 3 is a perspective view oi a detail oi mechanism for making the first bend. Fig. t is an elevation partly in section, showing how the completed article is discharged from the device. Fig. 5 is a iragmentary end view of a supporting arm for one of the loop forniers. Fig. 6 is an elevation oi the operating end thereof. Fig. 7 is a sectional view on the line 7? of Fig. l, showing a part of the irst loop former in elevation. Fig. 8 is an elevation of the saine showing another part oi this loop former. Fig. 9 is a plan of the loop former shown in Fig. 6. Fig. l0 is a plan on an enlarged scale ol the second loop former showing another position of the parts in dotted lines. Fig. 1l is a plan of the head carrying the mechanism for performing the lirst two operations on the jacquard needle, and Fig. l2 is a view ci a product which the machine is capable ci producing.

ln order to clearly show Vhe operations ot' the machine as it is illustrated, the jacquard needle to be formed will first be described, reference being had to Fig. i2. The needle a is formed from a piece of wire cut to delinite length. On its forward end it is provided with a bend l) and then the wire is bent around an axis c to form a loop d. Then a loop e is made which will be called the elongated loop as it is preferably made elongated in the direction of the wire, but oilset therefrom as indicated. This is accomplished first by bending the wire about an aXisf so as to bring it back parallel with the body 0l' the wire, and then bending it back on an axis g in the same direction so that the section 7L ofthe wire forms a continuation of the main body thereof, and the loop c is then completed.

Then a second loop or eye 7c is made by bending the wire about a single axis m. The rest of the wire from this point 0n is straight. lt will be seen that there are three sections of wire between the three loops (Z, c, and 7C, and beyond the latter all in alinement with each other, the three loops being formed on one side of the body of the jacquard needle. Although as has been stated, the invention may be employed for other purposes, it is herein described with particular reference to the manufacture of such a jacquard needle as that which has been described. Heretofore these jacquard needles have been made substantially by hand, some hand tools being employed for forming the bends, but of such a nature that the operation is slow and expensive. With this invention, even in such simple form as that illustrated, these needles can be made in substantially onesixth of the time heretofore consumed.

Referring now to the rest of the drawings, it will be seen that the invention is illustrated in a very simple form involving a pair of brackets 10 which may be secured to a bench or the like, and which carry a supporting bar 11 on which the entire operative part 0f the machine is carried. This support is shown in the form of a bar preferably of uniform cross-section so that the various parts of the device may be adjustable along it to suit the kind of article to be pro duced.

Reference is to be had now to Figs. 1, 2 and 11 which show a head 12 from which extends a strap 13 having a binding screw 14 by which the head may be secured on the supporting bar 11 in any desired position. Extending inwardly from the outer edge of this head, preferably at the top, is a guide 15 for receiving the end of the wire to be operated upon as indicated in Fig. 11. This guide has an inner wall 16 and an outer wall 17 between which the wire is placed. Slidably mounted in ways in the head is a bolt 18 which has a jaw 19 on its side, and is provided With a flat surface parallel with its direction of motion. When the wire is placed in the guide its end projects past the notch, the bolt being withdrawn as shown in Fig. 11. The i'irst operation of the machine is to force the jaw outwardly to bend the end of the wire to form the bend l). This leaves the bent end l) extending across the end of the wall 17 under the projection 20 on the jaw which holds it in position while the other o erations are performed. The motion of t ie bolt is accomplished by manipulating a lever 21 which is mounted to swing on a pivot supported by the head. This lever is provided with a projection 22 extending through a perforation 23 in the rear end of the jaw. This serves to reciprocate the bolt when the lever is turned, but in order to provide for giving the bolt a positive forward motion, to bend the end of the wire efficiently, the end of the lover is provided with a cam 24 which engages an inclined surface 25 on the jaw as the lever is raised to positively force the bolt outwardly and form the bend as indicated in dotted lines in Fig. 11. This is of course accomplished by the jaw 19 being forced past the wire so as to bend the same against the end of the wall 17. In the form shown, there is a cap plate 26 on the top of the head carrying the bolt, this cap-plate being removable for obvious purposes. ri"here is also an adjustable screw 27 located on the strap 13 for engagement with the lever when the same is dropped down to hold the lever in such position that the end 28 of the j will be flush with the end of the head, so as to receive the wire when the next operation is performed, as will now be described.

Wrhen the wire is first put into the inachine, as indicated in Fig. 11, it is guided and held in position not only by the walls 16 and 17, but by a pin. 30 and a jaw 31 located in line with these walls. This pin is stationary, and is mounted on a projection 32 on the head. The jaw 31 is mounted on a swinging lever 38 which turns about said pin as a center. On this lever also is a projecting arm 3a which has a notch 35 therein for receiving the wire. The lever has a handle 36 by which it may be turned on its axis, and when the end of the wire has been bent to form the bend l) this lever is turned as indicated in dotted lines in Fig. 11 through about 180 degrees so as to turn the wire about the pin 30 to form the bend at c and complete the loop d by swinging the wire through an are of 180 degrees against the end of the head and bolt. The notch 35, of course, engages the wire and helps to swing it around in this position, and in the end this motion presses it against the end of the jaw or head.

In order to provide for automatically returning the lever 33 to its normal position, as indicated in Fig. 11, it is provided with an arm 37 which, as well as the lever itself, has a bearing on a stud 38 concentric with the pin 30. A spring 39 is connected with this arm and with a stationary part of the device to return the parts to the position shown in Fig. 11. The main body of the wire new extends inwardly from the head 12 so as to ena loop-forming device carried by he support 11 which will new be described. This loop former comprises a plate or anvil 40, as indicated in Figs. 1, l and 10, reference also being had to Figs. 5, 7 and 8 for further details of this part of the machine. This carries a strap 4l surrounding the supporting bar 11 and secured thereon in adjusted position by a screw l2 or the like. From this strap a frame 43 extends outwardly at an angle to the supporting bar. On this frame is mounted a spring arm 114 which carries the main part of the loop-forming mechanism. This arm is preferably movably mounted on the frame so that normally it will be held out of operative position. For this purpose it is shown as being pivoted on a stud 45 at the end of the trame, and as being provided with a spring` 46 which normally holds the arm at an angle to the trame. t is also provided with a shield 47, the purpose of which will be described in connection with the description of the operation. This arm is adapted to project over the plate or anvil 40, and normally to be held up therefrom by its own resiliency. At its end it carries the main portions of the loop-forming mechanism which, as shown, comprises a swinging lever 50, to which is liXed astud 5l that rotates with it, on which is mounted a cam 52 adapted to engage the wire. A spring 53 normally holds the cam down. A handle 54 is provided for operating this lever. Under this handle is located a spring-pressed pin 55 adapted to engage the surface of the arm to assist in holding the lever in proper position when not in use.

lt will be seen that when the wire has been brought around into position to engage a pin 56, shown as supported on the plate 40, and the arm 44 has then been pressed down on the plate 40, the rotation of the lever 50 from the position shovm in full lines to that shown in dotted lines in Fig. 10, will cause the iiat side of this cam 52 to engage the wire, and turn it around the pin 56 to form a bend at f. This leaves the wire in the position shown in dotted.V lines, where it extends bael toward the head 12. During this operation the end of the wire is guided under the arm 44 by the guard 47. Now if it is desired to form an elongated loop at this point instead of a circular one, the further rotation of the lever 5G is caused to bend the Wire at another point instead of carrying it all the way around at this point, although obviously the parts so tar described by themselves could be used to continue the bend and form a circular loop or eye at this point entirely around the pin 56.

For the purpose of forming the elongated loop, an additional lever 60 is mounted on the arm 44. This lever is adapted to turn with a stud 61, on which is mounted a cam 62 lsimilar to the cam 52, but deeper and nor mally located in opposite position. New when the wire is brought around, as indicated above, it passes under the cam 62 and comes into contact with a second pin 63, shown as supported by the plate 40. The further rotation of the lever 5G causes a plate 64 on this lever to engage a roller 65 on the lever 60, and to turn the latter lever as the lever 5 is turned. Prior to this a cam 66 operates to engage the lever 50 and lift it so that the cam 52 will be brought up so as to ride over the wire during the rest of the rotation thereof. N ow the further rotation of the lever 5G will cause the lever 60 to be rotated and the cam 62 to take the wire around the pin 63 into a yposition parallel with its original position,

forming the bend at g and completing the elengated loop e. fi/Then the lever 60 reaches the position indicated in dotted lines in Fig. l0, this loop e having been completed, the lever 50 is released and the lever 6() is returned to its normal position by a spring 67, the lever 50 then being brought by hand back to its original position as shown in full lines.

it will be observed that the wire alter being bent in the head l2 comes into contact with the two pins 63 and 56. This is facilitated by a projection 68 on the head 40 having an inclined upper surface over which the wire may ride, and a straight inner surface for engaging the wire alter it slips over this inclined surface. The wire is really held between this flat surface and the pins on the head 40. This head is also provided with an extractor shown in Figs. l and 4, comprising a lever 7 6 having a head 7l located in a slot in the plate 40 between the pins 56 and 63, and adapted to receive the wire, so that it may be held in proper vertical position. lVhen the complete article is formed this lever is swung on its pivot as indicated in dotted lines in Fig. 4, to raise the wire oil the pins 56 and 63 and extract it from the machine.

It will be understood, o1" course, that the arm 44 is a spring arm, its own resiliency normally holding it up away from the pins so the wire may come into proper position against the pins without Contact with the cams on the under side of this arm. hen the wire comes into this position, the arm is lowered and guided into proper 1position by the pins entering holes in the arm. it is brought into and held in position by hand preferably.

in order to forni the circular loop 7s, the wire in the last position described comes over another plate or anvil 80 which has a projection Si thereon having an inclined upper surface and a riat guiding surl'ace like the projection 68. This plate or anvil 80 is similar to the plate 46, being fixed to the supporting bar ll in the same way. it is provided with a l'rame 8S and an arm 84, the details of which will not be described, as they are similar to the l'rame 43 and arm 44 respectively, except that the guard 47 may be omitted on the arm 84, as one guard may extend clearly across the space between the two frames and serve to guide the wire under both arms, i'or that is the purpose oi this guard. Gn this arm 84 is a lever 85 shown in Figs. l, 6 and 9, having a stud 86, cam 87, and pin 88. it will be seen that in this case the pin is supported by the arm instead of by the plate. However it will be obvious that the plate 8O might support the pin if desired. In either case the pin is guided in a hole 89 which is, of course,

located in the plate S0 il the pin is located on the arm. 1n order to 'form the circular loop or eye k, this arm is simply swung around 360 degrees as is indicated in the drawings. rfhis completes the formation oi' such a `iacipuard needle as shown in Fig. 12.

1t Will be seen that as the head and the tWo plates d() and 80 are adjustable along the supporting bar 11, the distance between the loops may be varied at Will, and in 'fact the tWo plates 40 and 8O may be interchanged iil desired, so that the elongated loop may come on the other side ol the circular loop, or either one may be used Without the other in accordance With the form oi the article to be produced. The same is true of the head.
